16-BIT CONSTANT CURRENT

LED SINK DRIVER



DESCRIPTION

The UTC L16B45 is designed for LED displays. UTC L16B45

contains a serial buffer and data latches which convert serial input

data into parallel output format. At UTC L16B45 output stage,

sixteen regulated current ports are designed to provide uniform and

variations.

UTC L16B45 provides users with great flexibility and device

performance while using UTC L16B45 in their system design for

LED display applications, e.g. LED panels. Users may adjust the

which gives users flexibility in controlling the light intensity of LEDs.

UTC L16B45 guarantees to endure maximum 17V at the output

port. The high clock frequency, 25MHz, also satisfies the system

requirements of high volume data transmission.


